How to use a soldering iron

Choose the right soldering tip: Choose soldering tips of different shapes and sizes according to your soldering needs.
Heating the soldering iron: Turn on the power and heat the soldering tip to the appropriate temperature (usually 300℃-400℃).
Cleaning the soldering tip: Wipe the soldering tip with a wet sponge or metal cleaning ball to remove the oxide layer and residual solder.
Soldering operation:
First, heat the soldering point (component pins and pads).
Touch the solder wire lightly to melt it evenly and cover the soldering point.
Continue heating for a while after removing the solder to fully wet the soldering point.
Remove the soldering iron and wait for the soldering point to cool and form a smooth and shiny soldering point.
Cleaning and maintenance:
Use a soldering iron stand to place the soldering iron on to prevent burns or damage to the work surface.
Turn off the power and store it after the temperature drops.
Replace or clean the soldering tip regularly to maintain good soldering results.
